My oil pressure has been dropping under load recently. I was told that the oil filter bypass might be stuck, and it would be better to just block it off anyway. Any tutorials on how to do this? A quick google search yielded nothing.
Some background on the oiling system...
I still have the stock corvette baffled oil pan, had the stock pump, recently replaced with a high volume, high pressure Melling pump. (same pressure drops with both pumps, so I dont think it is starving at the pickup). Pressure is 25lbs at idle and peaks to 70+lbs at 5000 RPM before dropping to 25lbs again. Valvoline 10/40 conventional with a WIX filter. Any other ideas as to what it might be besides the bypass? Pressure does not drop under hard braking/cornering either.
EDIT: The guy I spoke with showed me some sort of oil bypass that was blocked off. Im not talking about bypassing the one inside the filter itself. The piece he showed me was off of the motor, so Im not sure where it was located. I assume it was near the filter.
On a side note... Anyone else get rained on out in your vette this weekend? We had a major thunder/rain storm that came out of nowhere. Just washed it too... :crap:
